Method and mixer using the method for mixing a complex digital input vector with an oscillator reference signal based on a separation of the mixing process in mainly two processing steps, to with a first step in which a set of n real part values Vi, is derived from said complex digital input vector in which n is an integer larger than 1 and in which each real part value Vi is proportional to the real part of the digital input vector when being rotated over predetermined phase angles &phgr;i=&phgr;0+i*&Dgr;&phgr;, respectively, for a constant &phgr;0, &Dgr;&phgr; corresponding to either 2&pgr;/n or −2&pgr;/n, with integer i varying between 0 and n−1 and a second step, in which said n real part values and Vi are each consecutively selected to be coupled to a load. |
